蛋白结构(Molecular Characterization)

2B4 Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 23.1 kDa. The protein migrates as 35-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

2B4 SDS-PAGE

Human 2B4, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

2B4 ELISA

Immobilized Human 2B4, His Tag (Cat. No. 2B4-H5224) at 5 μg/mL (100 μL/well) can bind Human CD48, Fc Tag (Cat. No. BC1-H5255) with a linear range of 0.078-1.25 μg/mL (QC tested).

Protocol

 

背景(Background)

Natural killer cell receptor 2B4 is also known as NK cell type I receptor protein 2B4 (NKR2B4 or h2B4), SLAM family member 4 (SLAMF4), Signaling lymphocytic activation molecule 4, CD antigen CD244. NKR2B4 / CD244 contains two Ig-like (immunoglobulin-like) domains. CD244 is expressed in spleen, PBL, followed by lung, liver, testis and small intestine. CD244 interacts with CD48. Following phosphorylation, CD244 is able to recruit PTPN11/SHP-2 and SH2D1A/SAP. SLAMF4 modulate other receptor-ligand interactions to enhance leukocyte activation. CD244/2B4 is the only heterophilic receptor of SLAM family.
